Safe Operation Needs A Qualified Operator
WARNING
AVOID SERIOUS INJURY OR DEATH
Operators must receive instructions before
operating the machine. Untrained operators
can cause serious injury or death.
For an operator to be qualified, he or she
must not use drugs or alcoholic drinks
which impair alertness or coordination while
working. An operator who is taking
prescription drugs must get medical advice
to determine if he or she can safely operate
a machine and the equipment.
Operator Training
• Check the rules and regulations at your
location. The rules may include an employer’s
work safety requirements. Regulations may
apply to local driving requirements or use of a
Slow Moving Vehicle (SMV) emblem.
Regulations may identify a hazard such as a
utility line.
• The new operator must start in an area without
bystanders and use all the controls until he or
she can operate the machine safely under all
conditions of the work area.

12 Power Rake Operation and Maintenance Manual
Safety
Importance of Safety
Operating Safety
• Read and follow instructions in this manual and
the machine’s Operator’s Manual before
operating.
• This equipment is dangerous to persons
unfamiliar with its operation.
• Check for overhead and / or underground lines
before operating equipment (if applicable).
• In addition to the design and configuration of
equipment, hazard control and accident
prevention are dependent upon the
awareness, concern, prudence and proper
training of personnel involved in the operation,
transport, maintenance and storage of
equipment.
• Check that the attachment is securely fastened
to the machine.
• Make sure all the machine controls are in
NEUTRAL before starting the machine.
• Operate the equipment only from the
operator’s position.
• Operate the equipment according to the
Operator’s Manual.
• When learning to operate the equipment, do it
at a slow rate in an area clear of bystanders.
• DO NOT permit personnel to be in the work
area when operating the equipment.
• The equipment must be used ONLY on
approved machines.
• DO NOT modify the equipment in any way.
Unauthorized modification may impair the
function and / or safety and could affect the life
of the equipment. Affect or void warranty too.
• DO NOT make any adjustments or repairs on
the equipment while the machine is running.
• Keep shields and guards in place. Replace if
damaged.
• DO NOT operate equipment in poor visibility
conditions such as fog, darkness, or any
conditions that limit clear visibility less than 300
feet (100 m) in front of and to the sides of the
equipment.
• When conditions make it necessary to slow
ground speed, shift to a lower gear rather than
reducing engine speed. The engine will
maintain rated speed and keep the power rake
running at optimum speed.
• DO NOT operate in a work area that has not
been inspected for foreign debris and
obstacles.
• Remove any foreign objects and clearly mark
any objects that cannot be removed.
• Wear safety glasses, gloves, hearing
protection and other protective clothing when
required.
Machine Requirements And Capabilities
• The machine’s operator’s cab should be
equipped with a thermoplastic polycarbonate
or similar material front window, and similar
protection on the sides of the operator’s cab
before operating the equipment.
• Do Not exceed 4000 psi (275.8 bar) operating
pressure.
• Use caution on slopes and near banks and
ditches to prevent overturn.

Power Rake Operation and Maintenance Manual
Safety
Importance of Safety Cont’d
Fire Prevention Safety
• Flammable debris (leaves, grass, etc.) must be
removed regularly. If flammable debris is
allowed to accumulate, it can cause a fire
hazard. Clean often to avoid this accumulation.
• The equipment’s hydraulic motor compartment
must be inspected every day and cleaned if
necessary to prevent fire hazards and
overheating.
• All fuels, most lubricants and some coolant
mixtures are flammable. Flammable fluids that
are leaking or spilled onto hot surfaces or onto
electrical components can cause a fire.
Transporting Safety
• Comply with state and local laws governing
highway safety and movement of machinery
on public roads.
• Check local laws for all highway lighting and
marking requirements.
• Never allow riders on either machine or
equipment.
• If transporting the attachment on a truck or
trailer, make sure the it is properly secured to
the transport vehicle.
Hydraulic System
• Check hydraulic tubes, hoses and fittings for
damage and leakage. Never use open flame or
bare skin to check for leaks. Hydraulic tubes
and hoses must be properly routed and have
adequate support and secure clamps. Tighten
or replace any parts that show leakage.
• Always clean fluid spills. Do not use gasoline or
diesel fuel for cleaning parts. Use commercial
nonflammable solvents.
